Get your divMMCs while you can folks. Sings: Give me one good reason to keep making them, I'll give you ten good reasons to stop. too many broken Spectrums in the world, too many M1s that just don't work, too many broken Spectrums in the world, too many good divs they want to return

Anyboby know how many, or which of the new Spectum Next KS3 cores will be backported to the KS1 and KS2 models? Mainly wondering about the best core, the #zx81 @specnext.com ‬

15 years ago this month, I set up Tynemouth Software. So all this month, there is 15% off everything at my Tindie store. www.tindie.com/stores/tynem...

Can #chat-gpt generate a rouge level compilable in #z88dk for the #ZX81? First tests are kinda "yes".

Looking to start #RetroGameDev for the ZX Spectrum, ZX81 or Spectrum Next? My devcontainer makes this easy on Windows, Linux or MacOS. Now available on GitHub! github.com/mcphail/spec...

Anybody got #z88dk working under #termux in #android? Can get z88 to compile but when running a test build I get "Failed to create temporary filename"

New blog post - A ZX81 game running on a ZX81 emulator running on a Jupiter Ace emulator running on a Windows emulator running on a Linux PC. Or "modifying EightyOne to support the Minstrel 4th so I can debug it and find out why Tut-Tut does not work" blog.tynemouthsoftware.co.uk/2025/06/a-zx...

Moons ago, I made a tiny keyboard for Lorenzo Herrera’s Commodore Pet Mini – commodorepetmini.com – adapted into the Educator 64 Mini: www.zx81keyboardadventure.com/search/label... Now, thanks to Davidvro, printable keycaps finish the look: github.com/davidvrootech/c-educator-64-mini-keyboard-caps

Finally. Unmodified Tut-Tut for the ZX81 running on ZX81 BASIC for the Minstrel 4th running on a Jupiter Ace emulator running on a Windows 7 emulator running on a Linux PC. I am sure I will write an excessively long blog post about it. Thanks to @zx81keyboardadventure.com for helping sort this.

Seems an appropriate day to revisit some #forth -based games on #Minstrel4th, starting with #Tut-tut, which @zx81keyboardadventure.com inspired me to port to 100% Forth on #Ace / #Minstrel4th, here loaded from cassette tape cronosoft.fwscart.com/product/tut-...

New blog post - Finally fixing the VIC20 game Tornado. blog.tynemouthsoftware.co.uk/2025/03/fina... This is a nice VIC20 game, but a lot of the time, it would lock up as soon as it started. I have finally got to the bottom of why this happens, and the version on the Penultimate +3 now always works.

Having disassembled Colin Dooley's port of #centipede for the #JupiterAce (and #Minstrel4D), and discovered an unused spider graphic, I've been working to restore the spider feature and (hopefully) fulfil Colin's vision for this great game! I will share a TAP version soon. #retrogaming

That is very cool, but Wolfenstein 3D being the very first FPS is just a common misconception. It wasn't even the first FPS by id Software, who released Hovertank and Catacomb 3D in 1991.

Escape from PETSCII Castle - A Wolfenstein 3D inspiration but for the #CommodorePET by Jimbo www.indieretronews.com/2024/12/esca...

New blog post. Did anyone spot the Commodore bodge board on the early VIC20 board I repaired last week? Let's look into what that is doing, and how the video circuit changed over the years from the VIC-1001 to the VIC20-CR. blog.tynemouthsoftware.co.uk/2024/12/vic-...

That's got to be the coolest XMAS thing I've seen all year.

2024 RECAP: We went Behind the Pixels with Quantum Witch developer @nikkijay.games to learn more about her LGBTQ+ indie game which takes inspiration from classics like Metroid, Castlevania, & Link To The Past. We're really excited for it's release next year! Check it out:

I get a lot of inspiration and plenty of tips for repairing systems I’m unfamiliar with from blog posts like this. Plus they’re usually an interesting read.

Another experiment: #ZX81 loading a screen test file from an arduino mini via a parallel ZXIO card.

Tonight, stuffing around with the IO board on the #ZX81 / #Minstrel3 and an Arduino Pro Micro pushing in serial data.

Working with restrictive palettes is a lot of fun! Finished this lil CGA piece just in time for DOSember.

And that's a Monday done.

Currently working on this: NanoBeast is a pre-built 8-bit SBC for people who think the Raspberry Pi is "a bit much". Broadly MicroBeast compatible. 512K RAM, 512K Flash, RTC, I2C, USB-C power and data, GPIO, matrix keyboard decoder, dual UART and RC-Bus expansion. Repost if you want one!

I highly recommend grabbing yourself a copy of my latest Aquarius game 'Grid Trap' on physical cassette from Cronosoft https://buff.ly/3EvMcaZ but if you want a free digital version, then head over to my itch.io https://buff.ly/41arCIV

As it's nearly December here's your reminder that you can play my *FREE* #C64 puzzle game Grid Pix Advent. Play a level a day up to Xmas (or just bomb through them). The original game scored 88% in Retro Gamer. Don't be fooled by the easy start. #picross thalamusdigital.itch.io/grid-pix-adv...

My first computer

I haven't seen a single bad review for The Spectrum. I'm not sure if that's a good or bad thing—where's all the infighting, the drama, the mayhem? It just doesn't feel retro enough, there that's the problem!!!

Think I've finally found the perfect LCD monitor for the #ZX81 / #Minstrel3. It's got that mini desktop feeling.

Minstrel 3, it's more ZX81 than the #ZX81.
